## Discrepancy

PILOT FLEW 2.2 HOURS ON DRUG SURVEILLANCE FLIGHT.  UPON RETURN TO BASE, PILOT NOTED ON POST-FLIGHT, A LARGE PUDDLE OF OIL FORMING ON RAMP UNDER FIREWALL AREA.  SUBSEQUENT INVESTIGATION EXPOSED A CRACKED RUBBER 'SEAL' COUPLING BETWEEN OIL FILLER CAP AND OIL TANK.  THIS IS HIGH TEMPERATURE/HIGH PRESSURE AREA.  CRACK COULD HAVE RESULTED IN TOTAL LOSS OF ENGINE OIL.  SUBMITTER STATED PART SHOULD BE TIME-CHANGE ITEM AT APPROXIMATELY 3,000 HOUR INTERVALS.  PART CANNOT BE EXAMINED ON PRE-FLIGHT, OR PROPERLY INSPECTED AT 100-HOUR INSPECTIONS.
